Puzzle Overview

The shop team's frontend and backend deployments are both Ready in the `shop` namespace. The backend answers `/health` when you probe it from the right place, yet every request originating from a frontend pod to `backend:8080` hangs until it times out.

Nothing is CrashLooping. DNS resolves. The Service endpoints look fine. The failure is quieter than that — something in the cluster is deciding which traffic is allowed to reach the backend, and the frontend is on the wrong side of that decision.

Your job: restore frontend → backend connectivity so a request from a frontend pod to `http://backend:8080/health` succeeds.
